You are given a rule that relates x and y.
Substitute the x or y value you are given in each
ordered pair and solve for the unknown value, as follows:
-----------
2x+y=10
(5, )
You are told that x=5 and are asked to find the y value.
Substitute the 5 into the rule and solve for y as follows:
2(5)+y=10
10+y=10
y=0
